Adding swift3 to list of projects for particular ec2 job

Additional project should be added to PROJECTS as I understood.
It needs for clone the project to /opt/stack if this project enabled
for devstack.

Also, as Ian Wienand asked about regrouping definitions in patchset #1.
So I regrouped definitions in another job too to be similar.
